New Post: How to copy document from library to list attachment?

Hi!

I need to attach a document that is stored inside a document library to a list item on the same webpage. All needs to be done with javascript / jquery / spservices.

Can you please help me and show me how to do this?

I know, that SPServices has a function called 'AddAttachment', but I dont know how to get the file from the document library and pass it to this function.

Thanks!
